This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of cobalt. For each compound, a formal oxidation number for cobalt is given, but the usefulness of this number is limited for p-block elements in particular. read more
